Eros Corazza presents a fascinating investigation of the role that indexicals (e.g. 'I', 'she', 'this', 'today', 'here') play in our thought. Indexicality is crucial to the understanding of such puzzling issues as the nature of the self, the nature of perception, social interaction, psychological pathologies, and psychological development. Corazza draws on work from philosophy, linguistics, and psychology to illuminate this key aspect of the relation between mind and world. By highlighting how indexical thoughts are irreducible and intrinsically perspectival, Corazza shows (...) how we can depict someone else's indexical thought from a third-person perspective. The phenomenon of quasi-indexicality is introduced here: to represent Jane saying, "I am prosperous," we use what Castaneda termed a quasi-indicator in a report of the form "Jane said that she (herself) is prosperous". Corazza argues that quasi-indicators play such an important role in our linguistic, social, and psychological life that they have a cognitive primacy over other mechanisms of reference. Quasi-indexicality also emerges as a key notion when we come to consider our ability to understand other minds. Corazza argues that indexicality and quasi-indexicality are two sides of the same coin, best understood within the framework of direct reference. (shrink)

In 'You and She*' (ANALYSIS 51.3, June 1991) C.J.F. Williams notes the importance of reflexive pronouns in attributions of propositional attitudes, and claims to improve upon an earlier account of Hector-Neri Castaneda's in [1]. However, to the extent which his remarks are accurate, they reveal nothing that Castaneda hasn't already said, while insofar as they are new, they obliterate distinctions vital to Castaneda's theory. Castaneda called these pronouns quasi-indicators and noted that they function as linguistic devices used for attributing indexical (...) reference to others. For example, in hearing Arthur say 'I am wise' we would report his claim in English with, (1) Arthur thinks that he himself is wise. where 'he himself' is a quasi-indicator used to attribute to Arthur reference to himself qua self -- an expression that Castaneda abbreviated with 'he*.' Note that (1) is quite different from, (2) Arthur thinks that I am wise for 'I', functioning here as an indexical term, represents only the speaker's reference. Nor can (1) be identified with, (3) Arthur thinks that Arthur is wise. for this fails to represent the indexical character of Arthur's thought. Thus, (3) falls short of the informational content of (1). Moreover, as Williams, echoing Castaneda, points out, Arthur might not know that he himself is Arthur, or that he is named 'Arthur.' Hence, (3) might be false even if (1) is true. Williams observes that 'she' can also be used in oratio obliqua to report an indexical 1 usage, e.g., in (4) Arthur told Mary that she ought to talk to Shirley Makepeace's.. (shrink)

There are two ways of interpreting the argument for the existence of essential indexicals; one of them is too strong, the other one is compatible with reductionist positions.

It is widely agreed that the references of indexical expressions are fixed partly by their relations to contextual parameters such as the author, time, and place of the utterance. Because of this, indexicals are sometimes described as token-reflexive or utterance-reflexive in their semantics. But when we inquire into how indexicals help us to identify items within experience, we find that while utterance-reflexivity is essential to an interpretation of indexical tokens, it is not a factor in a speaker's identificatory use of (...) indexicals. Tokens cannot be interpreted unless they are first produced, and obviously the speaker who produces them does not depend upon utterance parameters in order to identify their referents in the way that hearers do. Consequently, the standard reflexive accounts of indexicals are of little use in explaining the speaker's identificatory use of indexicals, and must be either replaced or complemented by a further theory of the role of indexicals in thought. This paper provides an account of indexical identification that is attentive to a speaker's as well as a hearer's identification and reveals how indexicals are inextricably perspectival. (shrink)

According to Hector-Neri Castañeda, indexical reference is our most basic means of identifying the objects and events we experience and think about. Its tokens reveal our own part in the process by denoting what are "referred to as items present in experience" (Castañeda 1981, 285-6). If you hear me say, "Take that box over there and set it next to this box here," you learn something about my orientation towards the referents in a way that is not conveyed by, "Take (...) the red box and set it next to the blue box." My indexical tokens express what they do not only because they issue from a unique spatio-temporal perspective that I happen to occupy, but also because they reflect my encounter with referents that are differently situated in that perspective. From your perspective, my here might be your there, my you your she, and within my own, a this differs from a that and one this diverges from another. Encounter and orientation within a perspective are the essential ingredients in indexical identification without which particular 'this's, 'that's, 'then's, 'here's, and 'beyond's would be denuded of individuating powess.1 There are several consequences of this description. First, indexical reference is ephemeral because perspective is constantly changing, rendering the indexical status of an entity relative to a given perspective temporary: 1 A this quickly turns into a that, and soon enough it is lost to experience and is not even a remote that; a you goes away and is replaced by another . . . Nothing is really an enduring you -- except God perhaps for the abiding mystic. (Castañeda 1989a, 69) Second, indexical reference is irreducible since non-indexical mechanisms of reference fail to express the subject's involvement or encounter with the referents that indexicals convey. Nor can the various indexicals be reduced to each other.2 Third, because each perspective is unique, indexical reference is essentially subjective.. (shrink)

Indexical reference is personal, ephemeral, confrontational, and executive. Hence it is not reducible to nonindexical reference to what is not confronted. Conversely, nonindexical reference is not reducible to indexical reference. (Castañeda 1989, p. 70).

Throughout the last two decades, Newton da Costa and his collaborators have developed some frameworks to help the interpretation of science. Two of them are particularly noteworthy: partial structures and quasi-truth (that provide a way of accommodating the openness and partiality of scientific activity), and quasi-set theory (that allows one to take seriously the idea, put forward by several physicists, that we can't meaningfully apply the notion of identity to quantum particles). In this paper I explore the interconnection between these (...) two frameworks. After reviewing the extant formulations of quasi-truth and quasi-set theory, I suggest a way of combining them, advancing a formulation of quasi-truth in quasi-set theory. In this way, a good sense can be made of the idea that quantum mechanics, if not true, is at least quasi-true. I then explore an application of this combined framework, arguing that it provides a conceptual setting appropriate to overcome two (philosophical) difficulties in van Fraassen's modal interpretation of quantum mechanics.

Reference and indexicality are two central topics in the Philosophy of Language that are closely tied together. In the first part of this book, a description theory of reference is developed and contrasted with the prevailing direct reference view with the goal of laying out their advantages and disadvantages. The author defends his version of indirect reference against well-known objections raised by Kripke in Naming and Necessity and his successors, and also addresses linguistic aspects like compositionality. In the second part, (...) a detailed survey on indexical expressions is given based on a variety of typological data. Topics addressed are, among others: Kaplan's logic of demonstratives, conversational versus utterance context, context-shifting indexicals, the deictic center, token-reflexivity, vagueness of spatial and temporal indexicals, reference rules, and the epistemic and cognitive role of indexicals. From a descriptivist perspective on reference, various examples of simple and complex indexicals are analyzed in first-order predicate logic with reified contexts. A critical discussion of essential indexicality, de se readings of attitudes and accompanying puzzles rounds up the investigation. (shrink)

It has traditionally been maintained that every token of ‘I’ refers to its utterer. However, certain uses of indexicals conflict with this claim, and its counterparts with respect to ‘here’ and ‘now’, suggesting that the traditional account of indexical reference should be abandoned. In this paper, I examine some proposed alternatives and the difficulties they face, before offering a new account of indexical reference. I endorse Kaplan’s view that the reference of an indexical is determined on any occasion it is (...) used by applying its character to a particular context, arguing that the problem cases show that this is not always the context of utterance. The task facing the semantic theorist is thus to explain what fixes the reference-determining context. I consider and reject both Predelli’s suggestion that the reference-determining context is the one intended by the utterer, and Corazza et al.’s proposal that the relevant context is fixed by conventions delivered by the utterance setting. The discussion of these two accounts reveals that an adequate theory of indexical reference should allow the speaker to use indexicals in novel ways, whilst holding that what a speaker can refer to with an indexical utterance is constrained by what an audience can understand. I develop an account based around these two requirements. (shrink)
